CONSERVATION STATUS

The Canvasback is native to Mexico, Puerto Rico, Cuba, Canada, Bermuda, the United States, Honduras and Guatemala. It is also known to be seen in various countries throughout the Pacific and the Caribbean in addition to the United Kingdom. The range of this bird is about 5 million square kilometers. The global population of the Canvasback is about 600,000 individual birds. Currently, this bird species is rated as Least Concern and there are no immediate concerns regarding the Canvasback.

SUMMARY

Overview

Canvasback: This is a large, flashy diving duck with a pale gray body, black breast and tail and gray legs and feet. The head is red-brown with a long sloping profile, a long dark bill and red eyes. It feeds primarily on aquatic plants. It has a rapid direct flight with strong wing beats and flies high, usually in V- formations.

Range and Habitat

Canvasback: Breeds from Alaska south and east to Nebraska and Minnesota. Spends winters in coastal regions and interior west from British Columbia south and east from Massachusetts south to the Gulf Coast, across to the Mississippi Valley, and throughout the southern states. Nests on marshes; winters on lakes, bays, and estuaries.

INTERESTING FACTS

Because they strain many seeds with their bill out of bottom mud, they ingest much lead shot and are especially affected by lead poisoning in areas that are heavily hunted.

One of the largest North American diving ducks, it gets its name from its pale gray back and white sides which are delicately dotted and lined in a wavelike pattern resembling canvas fabric.

The Canvasback is a very good flier and can reach speeds of up to 70 mph.

A group of ducks has many collective nouns, including a "brace", "flush", "paddling", "raft", and "team" of ducks.

FAMILY DESCRIPTION

Ducks, Geese and Swans (Anatidae)

ORDER

The ANSERIFORMES (pronounced an-ser-ih-FOR-meez), one of the oldest avian orders, is composed of three families and includes the bizarre and noisy screamers of South America, the odd Magpie Goose of Australia, and the globally distributed swans, geese and ducks.

FAMILY TAXONOMY

The swans, geese and ducks are grouped in the Anatidae (pronounced ah-NAH-tih-dee); a bird family with one hundred sixty-four species in forty-eight genera, various members of which can be found on all continents.

NORTH AMERICA

The Anatidae are represented in North America by sixty-nine species in twenty-three genera (including the extinct Labrador Duck). Members of this well known bird family include the graceful, long-necked swans, familiar geese of farm fields and golf courses, and the many species of ducks.

KNOWN FOR

While all species are known for their association with aquatic habitats, Canada Geese are also known for their aggressive behavior when guarding their nests and young. After the breeding season, Canada Geese become better known for the "V" shaped flocks they form during migration.

PHYSICAL

Swans, geese, and ducks are large birds with long necks (longest in swans, shortest in ducks) and short tails. All species have webbed feet suited to their aquatic environments and distinctive flat bills - except for the mergansers with their thin, serrated bills ideally suited for catching fish.

COLORATION

Although swans and geese are mostly white, brown, and black, many ducks showcase several shades of grays, browns, and blacks combined with fine barring and streaking to result in a variety of beautifully patterned plumages for which females of the species are well known. Males in breeding plumage are more boldly patterned and often have iridescent blue or green on the head. Both sexes usually show a spot of color in the wing known as a "speculum".

GEOGRAPHIC HABITAT

Swans, geese, and ducks occur throughout North America wherever aquatic habitats are found. While geese and some ducks are often found along the shoreline, species that feed on underwater vegetation such as swans and dabbling ducks prefer calm water with depths suited to the length of their necks. In deeper waters, the mergansers, scoters, and diving ducks occur. Boldly-patterned Harlequin Ducks swim in the swift rivers and turbulent seashores of the Pacific Northwest and some areas of the northeastern U.S. and Canada.

MIGRATION

A highly migratory family, most species migrate to open, ice-free water in sheltered bays and marshes of the southern United States with some reaching Mexico and Central America.

HABITS

Members of the Anatidae flock together after breeding in large, multi-species groups at sites with good, safe foraging. At such sites, scoters, Canvasbacks, and other diving ducks dive for mussels in the deep sections while dabblers such as Gadwall and Northern Shovelers forage on the surface and in the shallows. On the shore, grazers such as geese and the American Widgeon forage on grass.

CONSERVATION

Populations of two Alaskan diving ducks, the Steller's and Spectacled Eiders, are threatened for reasons unknown; possible causes include changes in their habitats, nest predation by ravens and gulls, hunting, and the on-going effects of lead poisoning. The reasons why the Hawaiian Goose, and the Laysan and Hawaiian Ducks are endangered are much better understood; however after nearly going extinct, populations have stabilized but unfortunately don't have much room for growth in the limited amount of available habitat.

INTERESTING FACTS

The white plumage of Snow Geese and Tundra Swans sometimes takes on a dirty, rusty-brown appearance. The birds aren't actually dirty but do show rust-colored highlights from foraging in the iron rich environments of the far north. Regarding the well-known description of the sound made by a duck as a "quack," duck species in North America also variously whistle, squeak, click, and grunt.
